Function
(1) XCALL instruction executes the subroutine program and performs non-execution processing
of the subroutine program.
(a) Execution of subroutine program
Executes each coil instruction according to ON/OFF status of the condition contacts.
(b) Non-execution of subroutine program
Performs the same processing for each coil instruction as when the condition contacts
are OFF status. The operation results for the individual coil instructions following
non-execution processing will be as follows,
regardless of the ON/OFF status of the individual contacts:
OUT instruction
SET instruction
RST instruction
SFT instruction
Basic instructions
Application instructions
PLS instruction
